ROSE-ENGINE `i?ECIFIGATIOIl' forming part of Letters Patent No. 314,064, elated March 17, 1885. i
Application ii'ed January l5, i985. (No model.)
To @ZZ whom, it may concern.-
Beit known that I, ANTON SeH'WrT'rne, a citizen ofthe United States, residing at Brooklyn, in the county ot' Kings and State of New York, have invented new and useful Improvements in Roselngines, oil which the following is a specification.
This invention relates to a rose-engine which produces rectilinear designs or designs composed of ri ghtlines,in contradistinction to roseengines which produce curvilinear designs.
My present invention consists in the combination, with the graver or tool-support, of the pattern-slide, the screw-spindle for imparting to this slide the required motion, the Work -support, the carriage supporting the pattern-slide and the work-support, the tracerslide, a stop which retains the graver out of Contact with the work when the tracer is opposite to oneof the high portions of the pattern, and means for imparting to the carriage a reciprocating motion, so that by imparting to the carriage, the graver-support, and the pattern-slide the required movements the de; sign contained on the face of the pattern is reproduced upon the face of the work. With the tracer-slide and the carriage is combined a pantograph connection for changing the scale of the reproduced design. cured to an arm, which is hinged to the tracerslide and which bears upon a projection eX- tending from the graversupport, so that the osition of the 0raver in reward to th'e Work b b is automatically controlled by the action of the tracer upon the pattern.
In the accompanying drawings. Figure l represents a sectional front view of my roseengine, the plane of section being indicated by the line x x, Fig. 2. Fig. 2 is a longitudinal vertical section in the plane y y, Fig. l. Fig. 3 is a horizontal section in the plane z a, Fig. l. Fig. 4 is a face view of the pattern on a larger scale than the previous figures. Fig'. 5 is a face View ofthe Work produced from this pattern when one-half of said work has been finished. y
Similar letters indicate corresponding parts.
In these drawings, the letter A designates a frame, into whichV is lit-ted the carriage B, so
5o that said carriage can be moved up and down.
Various means may be used for imparting to The tracer is se-` the carriage this up-and-dow'n movementsuch as a rack and pinion or suitable levers.
ln the example represented by the drawings l have shown a spindle, C, which has its bearings in the head D, and on which is mounted a drum, E, from which extends a rope, cord, or chain, c, to the carriage B. From this carriage extends another rope, cord, or chain, b, over one or more pulleys, c, and to the free end of this rope is secured a weight, e. This `weight slightly overbalances the weight of the carriage with all the parts connected to it, and when the spindle C is turned so as to wind up the rope a on the drum E, the earriage is depressed; but if the spindle is turned in the opposite direction the carriage is raised by the action of the weight. The spindle C is turned by a treadle, which connects by a belt with a pulley,f, mounted on the spindle, (the belt and treadle being not shown in the drawings.)
On the carriage B are mounted the Worksupport F and the pattern-slide G. In the example shown in the drawings the Work-support is secured to a. slide, II, which is fitted into guideways extending transversely across the carriage; but it' it is desired to reproduce on the work only rectilinear designs, the work-support may be rigidly secured to the carriage. The patternslide G lits into guideways g, formed in the carriage or in a casting firmly secured to said carriage, and a screwspindle, I, serves to impart to said pattern slide a movement transversely to the carriage or in a direction at right angles to the rising and falling movement of said carriage.
On the pattern-slide is firmly secured the pattern J, on the face of which is engraved, etched, or otherwise produced a counterpart of the design which is to he reproduced on the face of the ivorlthat is to say, if the work is to be ornamented by diamonds produced by rightlines of gradually increasing and decreasing length, leaving diamond shaped blank spaces between them, as indicated in Fig. 5, the pattern consists of diamonds which are alternately raised and depressed, and when the tracer moves over one ot' the depressed panels or sections of the pattern, the graver produces the lines on the work,\vhile, when the tracer moves over one of the raised panels or sections of the pattern, the graver is pushed away from the work, as will be presently more fully explained.
The tracer h is secured in an arm, I,which is hinged to they tracer-slide L, so that when the tracer is moved over the face of the pattern, it can fall into the depressed panels or recede, so as to move over the raised panels of the pattern. The tracer-slide L moves up and down in guideways z', Fig. 3, formed ina standard, M, which is firmly secured to the base supporting the frame A, and it connects by the rod N, lever O, and link I) with the carriage B. The lever O has its fulcrum on a pivot, j, which can be adjusted in a slot, Zr, so that by movingthe carriageB up and down more or less motion is imparted to the tracer"- slide L. If the fulcrum j is adjusted directly in the middle of the lever O and the carriage B is depressed, the tracerslide moves np just as much as the carriage moves down; but when the fulcrumj is moved toward the outer end of the lever O, the movement of the tracerslide is decreased, and vice versa, and by increasing the movement of the tracer-slide the scale of the design produced on the work is reduced, and vice versa. lf it is desired to enlarge the scale of the design produced on the Work, the fulcrum j of thev lever O must be placed in an extension of said lever beyond its connection with the rod N.
I have termed the rod N, lever O, link l?, and the adjustable fulcrnm j of the lever O the pantograph connection between the carriage and the tracer-slide.
The arm K,which carries the tracer h, bears upon a pin, Z, which is secured in an arm, m, projecting from the support Q of the graver n. The supportis of well-known construction, and it can be moved toward and fromthe work in guideways o, and also across the work in guideways p.
Then the operation commences, the tracer is supposed to be opposite one of the depressed panels in the pattern and the tool support is forced inward by a slight pressure of the hand or otherwise, so that the pin Z bears upon the arm K of the tracer and that the graver bears upon the work. The carriage is then depressed and allowed to rise, and the graver produces the first line on the left-hand side of the work, Fig. 5; then the pattern-slide is moved in the direction of arrow l, Fig. l, and the graver is moved in the opposite direction, as indicated by arrow 2, the carriage B is again depressed and allowed to rise, and ther second line is produced on the work. As the operation progresses the lines produced on the work by the graver become broken, because whenever-the tracer passes over one of the raised panels of the pattern, the graver is, by the action of the arm K on the pin Z, forced back out of contact with the work; but for each down-and-up stroke of the carriage the graver is carried up and down over the entire face of the work.
The pin Z, secured to the arm m of the graversupport Q, bears against the arm K, which carries the tracer 71 and these devices, orequivalent, constitute what I term a stop,7 which, by pushing on the graver-support, retains the graver out of contact with the work when the tracer is opposite to one of the high portions of the pattern.
What I claim as new, and desire to secure by Letters Patent, is-
1. The combination, substantially as hereinbefore described, with the graver-support, of the pattern-slide, the screw-spindle for imparting to this slide the requisite motion, the work-support, the carriage supporting the pattern-slide and the work-support, the tracer-slide, the stop which retains the graver out of contact with the work when the tracer is opposite to one of the high portions of the pattern, and means for imparting to the carriage a reciprocating motion. v
2. The combination, substantially as hereinbefore described, with the graver-support, of the pattern-slide, the screwspindle for imparting to this slide the requisite motion, the work-support, the carriage supporting the pattern-slide and the work-support, the tracer-slide, the stop which retains the graver out of contact with the work when the tracer is opposite to one of the high portions of the pattern, the pantograph connection between the carriage and the tracerslide, and means for imparting to the carriage a reciprocating motion.
3. rlhe combination, substantially as hereinbefore described, with the graver-support, of the pattern-slide,'the screw-spindle for imparting to the slide the requisite motion, the work-support, the carriage supporting the pattern-slide and the work-support, the tracerslide, the arm hinged to the tracer-slide and carrying the tracer, the pin projecting from the graver-support and bearing on said arm, and means for imparting to the carriage a reciprocating motion.
4. The combination, substantially as l1ereinbefore described, with the graver-support, of the pattern-slide, the screw-spindle for imparting to the slide the requisite motion, the work-support, the carriage supporting the pattern-slide and the work-support, the tracer-slide, the arm hinged to thetracer-slide and carrying the tracer, the pin projecting from the graver-support and bearing on said arm, the pantograph connection between the carriage and the tracer-slide, and means for imparting to the carriage a reciprocating motion.
In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
ANTON sonwir'rnn.
